What

Diagnostics from the IDE MCP server that report severity as a word rather than a number are now understood instead of being dropped.

Details
  • a new lookup lowercases the string and maps error, warning, info, information and hint to the canonical form
  • non-strings and unrecognised values yield no severity
  • the mapping table is absent from the previous build
Evidence

information

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
